Been running the PC III on the past several bikes with satisfaction. Got an '08 Glide with the TC96, S/E air filter and Wild Pigs slip ons - and, of course a Power Commander III USB.

I just got the bike before Bike Week and didn't want to break in a new engine sitting in traffic so I brought the Street Bob down to Daytona this trip. While there I met one of the notebook computer toting "techs" at Miller's Parts down on Route 1 in South Daytona. While they were busy screwing up my buddy's bike (that will be a whole separate thread) I was talking to the Power Commander guru they had there - you know, the guy running around with the notebook computer pretending he knew everything. I get talking with him and share with him my meager set-up. He asks me what map setting(s) I'm running and I said, just the ones that George Miller wrote on the box when he shipped me the Wild Pigs thatI originally had on my '06 RKC.

He looked at me and said, "You're kidding, right."
I said, "I'm not kidding. I'm just breaking her in but she seems to run fine."

He said that the settings for the '06 will not work right in the '08 and thatI have to change the settings to one of the '08 maps. He scrolled through his '08 touring maps; there were not many and said, "Here ya go - use this one." It was for S/E Stage 1 air filter and Samson Slip ons.

Well as soon as I got back from Daytona I loaded the exact map that he told me. Now, the bike seems OK (nothing great) in low and maybe mid but anything near wide open she is a dog! Matter of fact, I took her out the other day and did some WFO runs. The bike would not go past 92mph and would actually seem to run a little stronger off of WFO. The 92 mph top speed was with just me on the bike, no luggage, 3/4 fueland going both ways on the highway so as to average out what was (one way) a stiff headwind.

When I got back to the house and parked the bike, the right pipe was black with soot. Don't even want to think what my plugs, heads, valves and the like look like. She's way too fat.
I know from flying piston engined aircraft that power comes at a lean setting - but not too lean. She pushing too much fuel at WO throttle positions. Anybody have any suggesitons?

I'll be calling Dyna Jet but wanted to run this past the brain trust here. Besides - you guys are open on a Sunday evening!

Thanks in advance.

 

yep, sounds like it it too rich.
If it were mine, i would load the default mapping (the one that was there before your screw up) back into the unit and leave it at that. Get a dyno run and have a custom map built to suit your driving habits.

 

John, Thanks for the reply.

The problem is I never did any sustained full throttle runs with the original setting because I was just loading and unloading at moderate power settings and only going to FT momentarily - just seating rings,providing heating and cooling cycles and letting new moving parts get to know their close neighbors.

I eventually got enough miles on the bike where I felt comfortable hammering it and that the runs referenced above. The original settings were sent to me by George Miller - back in the good days when his family ran Miller's and they were good. "Wild Pigs" were his creation and the map setting he provided was what he had seen working on dressers using only the Stage 1 air cleaner. That was in '06 and my '06 RKC ran great with that set-up. Other than a 9% increase in displacement - I am not really familiar with what other changes there are between the TC88 and the TC96 that would require significant fuel delivery changes.

I'll report back onceI know more.
